PoisonTap is built for the $5 Raspberry Pi Zero without any additional components other than a micro-USB cable & microSD card, or can work on any Raspberry Pi (1/2/3) with an Ethernet-to-USB/Thunderbolt dongle, or can work on other devices that can emulate USB gadgets such as USB Armory and LAN Turtle.

When PoisonTap (Raspberry Pi Zero & Node.js) is plugged into a locked/password protected computer, it:
emulates an Ethernet device over USB (or Thunderbolt)
hijacks all Internet traffic from the machine (despite being a low priority/unknown network interface)
siphons and stores HTTP cookies and sessions from the web browser for the top 1,000,000 websites
exposes the internal router to the attacker, making it accessible remotely via outbound WebSocket and DNS rebinding (thanks Matt Austin for rebinding idea!)
installs a persistent web-based backdoor in HTTP cache for hundreds of thousands of domains and common Javascript CDN URLs, all with access to the user’s cookies via cache poisoning
allows attacker to remotely force the user to make HTTP requests and proxy back responses (GET & POSTs) with the user’s cookies on any backdoored domain
does not require the machine to be unlocked
backdoors and remote access persist even after device is removed.

What you want in the spoiler then close with [\spoiler]

OK so it "kinda" works in code tags (cannot see whats inside though)
Also seems it only kind of works in message preview not in actual posted information.
We don't need to but for research sake,
let's try something else .

ensō, are symbols of teaching, reality, enlightenment, and a myriad of things in between.

Seemingly perfect in their continuity, balance, and sense of completeness, and yet often irregular in execution, ensō are at once the most fundamentally simple and the most complex shape.
They seem to leave little room for variation, and yet in the hands of Zen masters, the varieties of personal expression are endless.
Ensō evoke power, dynamism, charm, humor, drama, and stillness.
